Abstract

Abstract Methods and compositions for identifying and characterizing one or more ligands of a peptide are provided. In particular, the invention provides a phage ligand sensor device (PLSD) comprising a sensor coupled to a binding element of interest. Binding elements of interest comprise phage displaying at least one foreign peptide. The PLSD and assays find particular use in identifying and characterizing ligand-peptide interactions.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 114 words
A phage ligand sensor device comprising: a) a sensor comprising a piezoelectric crystal; and b) a binding element comprising engineered phage, wherein said binding element is capable of binding to a ligand that is Bacillus anthracis bacteria or spores, wherein said phage have been engineered to express a foreign peptide known to bind to said Bacillus anthracis bacteria or spores, and wherein said foreign peptide comprises an amino acid sequence selected from the group consisting of DPRTVSTA (SEQ ID NO:8), DRTSSNTT (SEQ ID NO:9), DRSASSTA (SEQ ID NO:10), DRTSQNLQ (SEQ ID NO:11), DRSGTSPS (SEQ ID NO:12), DRNVNGPS (SEQ ID NO:13), ERGSNATL (SEQ ID NO:14), DSRNEKSM (SEQ ID NO: 15), ESRNSPAA (SEQ ID NO: 16).
Claim 2
Dependent Claim 114 words
A phage ligand sensor device comprising: a) a sensor comprising a piezoelectric crystal; and b) a binding element comprising engineered phage, wherein said binding element is capable of binding to a ligand that is Bacillus anthracis bacteria or spores, wherein said phage have been engineered to express a foreign peptide known to bind to said Bacillus anthracis bacteria or spores, and wherein said foreign peptide comprises an amino acid sequence selected from the group consisting of DPRTVSTA (SEQ ID NO:8), DRTSSNTT (SEQ ID NO:9), DRSASSTA (SEQ ID NO:10), DRTSQNLQ (SEQ ID NO:11), DRSGTSPS (SEQ ID NO:12), DRNVNGPS (SEQ ID NO:13), ERGSNATL (SEQ ID NO:14), DSRNEKSM (SEQ ID NO: 15), ESRNSPAA (SEQ ID NO: 16).
Claim 3
Dependent Claim 24 words
